Participants

Reaction Steps

Hydrogen sulfide was blown into an ethanol solution containing 1.4 g of the N-(cyano-2-furanylmethyl)-1-methyl-1H-pyrazol-4-carboxamide as obtained in the above process and 0.7 g of triethylamine, for 1 hour, and the whole was stirred for 1 hour under cooling with ice and then for a further 2 hours at room temperature. Afterwards, the crystal formed was taken out by filtration, washed with chloroform and then dried, to obtain 1.1 g of the intended N-[2-furanyl(thiocarbamoyl)-methyl]-1-methyl-1H-pyrazole-4-carboxamide.
